Background
The Chinese college student's equation automobile tournament is an automobile design and manufacturing competition participated in by college student teams by related specialties of higher colleges. Each racing car team designs and manufactures a small-sized single-seat leisure racing car within one year according to the racing rules and the racing car manufacturing standards, and the racing in the racing link can be successfully completed. The events are divided into oil car groups, electric car groups and unmanned car groups. The electric vehicle adopts three driving schemes of single motor, double motors and four-motor driving.
In recent years, a fleet of four-motor drives has increased year by year due to their excellent performance in terms of power, operability, and the like.
Four motors are used for driving four wheels respectively and directly, a traditional mechanical differential is omitted, when the four wheels are steered or driven on an uneven road surface, the outer wheel is required to rotate faster than the inner wheel, if the inner wheel and the outer wheel are still used for outputting the same torque, the ground gripping performance of the tires cannot be fully exerted, the vehicle can be steered excessively and understeer, the stress condition of parts of a reduction gearbox is severe, and the like, so that adverse effects are caused on the vehicle operation stability.
To solve this problem, mounting an electronic differential system on a vehicle is a main solution. In this regard, many control strategies have been applied. For example, target values of the rotating speeds of the inner wheel and the outer wheel are obtained based on an ackerman steering model, and then the rotating speed of the driving wheel is controlled by adopting PI control or sliding mode control.
Although the above work has made a great progress in improving the vehicle performance, the advantage that the four-motor-driven racing car can directly and individually control the driving torque of each wheel is not fully exerted, and the problem of whether the tire performance is fully exerted is not fully considered. Therefore, in order to improve the vehicle handling stability, it is conceivable to perform an electronic differential by using torque control. Therefore, the invention provides an electronic differential algorithm of a four-motor-driven FSAE racing car based on sliding mode control to solve the problems in the background art.
